Dad-of-three Paul Hartshorn has spent six months treading some of Britain’s toughest terrain, and on Sunday he’s off to Exmoor for the next step of the journey.

The reason? Paul, 49, has been completing a series of demanding “ultra-run” races for children’s charity Starlight.

Sunday will see him covering a 37-mile route that takes in 7,600 feet of vertical ascent.

But the next couple of months will make that race seem pedestrian.

“On June 22 I’m doing the UK’s hardest non-stop point to point race – the Ultra Trail South West,” the Tarnworth Road, Harold Hill, resident told the Recorder.

“They give you up to 20 hours. It’s just over 13,600 feet of vertical ascent.

“People come from all over the world to do it. It’s the UK’s hardest non-stop point to point race.

“I’ve done Ben Nevis and Snowdon and it blows them out of the water.”
